Improvement in bungs and bung-inserters



DANIEL BOONE 'RIOKEY, OF SAN FRANCISCO, CALIFORNIA.

IMPROVEMENT-IN BUNG,S AND BUNG-INSERTERS.

Specification forming part of Letters Patent No. 119,094, dated September 19, 1871.

, in whicha metallic ring or bushing is rst screwed into the barrel-stave andthe metal bung afterward screwed into the ring, and it consists, rst, in providing a novel tool for the purpose of inserting the metallic ring or bushing into the barrel-stave, by the use of which l accomplish several very useful results, (this tool I call a bung inscrterg)n and secondly, in an improved construction of the bushing, which construction is permitted by the use of my bung-inserter.

, In order to more fully explain my invention,

reference is had to the accompanying` drawing forming a part of this speciiication, in which- Figure 1 represents a side elevation of the bung-inserter. Fig. 2 is a plan of the bung-inl serter. Fig. 3 is a perspective of the ring employed on the inserter. Fig. 4. is a sectional elevation of the bushing with the bung-inserter. Fig. 5 is a sectional elevation of the bung, showing the manner of securing the washer.

Like lletters indicate like parts in the drawing.

A is the metallic ring or washer, which is provided with internal and external screw-threads in the ordinary manner. This ring I make slightly conical or tapering, as shown at Fig. el; and I make the threads narrow at the base and quite sharp, so that when the bushing is bored into a hole of the proper size it ywill cut its own threads. This I am permitted to do by means of my bung-inserter B. 'Ihis inserter consists of a metal standard, C, through the upper end of which a hole, d, passes. 'Ihe base E of this standard is made of the same size as the bung, and is provided with screw-threads, as shown. Resting upon the base E, and encircling the standard G, is a ring, f, in the upper face of washer.

which, and opposite each other, are two oppositely-inclined depressions, g, shown plainly at Fig. 3, and passing through the standard, so that its opposite ends will rest in these depressions, is a bar, t', shown at Fig. 2.

To use this inserter the base E is rst screwed into the bushing until the ring f is brought down near its face. The standard C is then Vturned until the ends of the bart' rest as far as possible up the incline of the depressions. The base is then screwed down until the ring rests upon the face of the bushing. A proper-sized hole having been irst made in the barrel-stave by means of a bung-borer, the bushing is started into it, when, by placing a rod through the hole d and using it as a lever, the bushing can be screwed into the hole in the stave until it is snugly down 5 and when once it has been thus forced down so as to out its own thread it cannot be started by ordinary means, and will not leak. After the bushing has been firmly screwed down the inserter can be readily removed by turning the standard G in a reverse direction, which causes the bart to move to the lowest part of the depression and relieves the pressure on the screw.

On the under side of the bung P a portion is cut away around its periphery so as to form a seat for a leather washer, which is bound between this seat and the projecting seat m on the In the ordinary bung this washer is merely placed on the seat m and the bung screwed down upon it, thus leaving it free to be washed out every time that the barrel is cleansed. In order to iix thiswasherI turn achannel, n, around the downward-projeotin g portion of the bung, into which the washer can be stretched, and from which it cannot easily be removed, thus iiXing the two together and rendering its presence at all times certain.

By this means of inserting the bushing I am enabled to do away with any surplus metal above the face of the stave which is ordinarily required to give a hold for the spanner used for inserting them, not only rendering the bung more sightly, but doing away with that portion of the work required for fitting this face to the stave 5 and by constructing the bushing so that it will cut its own threads it is rendered perfectly tight and In Witness that the above-described invention reliable. is claimed by me I have hereunto set my hand Having thus described my invention, What I and seal.
